Denis, Nancy - if you can find the message within the autosave directory then
please take a look at the bug #230466, I think that one is your case

meanwhile, after some experimenting ... the initial bug description is not
correct, and also the subject - what really happens to me and how to reproduce:

1. start kmail
2. set some autosave time like e.g. 5 minutes
3. create a new message, write some text into it
4. wait until the message gets saved, check the
~/.kde4/share/apps/kmail/autosave/cur directory
5. kill kmail
6. check ~/.kde4/share/apps/kmail/autosave/cur directory - the autosaved
message is still there
6. start kmail
7. the new message may or may not appear in the editor, depending whether you
hit bug #230466

if the message does not appear in the editor:
8. the chance is that you can find the autosaved message in the
~/.kde4/share/apps/kmail/autosave/cur directory

if the message appears in the editor:
8. the autosaved message disappears from the
~/.kde4/share/apps/kmail/autosave/cur directory
9. kill kmail before the autosave timeout is reached
10. boom, you've just lost all your work, the message is not stored anywhere

eventually, you can hit bug #230466 in the way that the message is not opened
in the editor AND the message gets deleted anyways

what needs to be changed - the message should not be deleted from the autosave
directory before a new copy is saved, otherwise the crash/network
disconnect/power failure/whatever can hit the time frame when there is no copy
of the message stored on a harddisk

I'd also suggest autosaving immediately after the new message creation and not
waiting for the timeout at first - imagine a case of a reply quoting the
previous email on an imap server which may get deleted meanwhile and if you
cannot restore the reply, you've lost the quoted text forever

below there is a part of kmail console log regarding autosaves - what is
interesting, there is no mention of the message '1279102908.4061.ZHE4K' (my
testing message) being deleted but kmail tries to delete
'1279103354.7912.S3zV1' which did not exist anytime during my experiments
(rather than listing the ~/.kde4/share/apps/kmail/autosave/cur directory, I've
used 'find' to list everything under ~/.kde4/share/apps/kmail/autosave)

(oh, and why the autosave index gets created twice?)
